Question 1

How do I use this tool?

Accepted Answer

Pick a target keyword, then paste the raw HTML of the top 3 ranking pages (right-click → View Page Source → copy). The tool extracts word count, heading structure, keyword usage, meta tags, and content gaps — then builds a comparison report you can copy as Markdown.

Question 2

What is a content gap?

Accepted Answer

A content gap is a heading or sub-topic that appears in competitors' content but not in yours. If 2 of 3 competitors have an H2 titled 'Pricing' and your content doesn't, that's a gap to fill. This tool flags headings that appear in multiple competitors but not in your primary HTML.

Question 3

Does this tool fetch pages from the web?

Accepted Answer

No — it's 100% client-side and offline-capable. You paste the HTML yourself. We never make network requests. This keeps you in control and avoids CORS / rate-limit issues.

Question 4

What extra features does this tool have compared to others?

Accepted Answer

(1) Multi-competitor comparison (up to 3). (2) Word count comparison per competitor. (3) Heading structure extraction (H1-H6). (4) Keyword density per competitor. (5) Content gap detection (headings in competitors but not yours). (6) Stats summary table. (7) Export as Markdown report. (8) Copy report. (9) History (localStorage, last 20). (10) Shareable URL.

Question 5

Is my data sent anywhere?

Accepted Answer

No. HTML parsing runs locally. History is stored in localStorage on this device only.
